Since advanced glycation end-products (AGEs) inhibitors such as benfotiamine, pyridoxamine and aminoguanidine significantly inhibit the development of retinopathy and neuropathy in streptozotocin-induced diabetic rats, treatment with AGEs inhibitors is believed to be a potential strategy for preventing lifestyle-related diseases such as diabetic complications and atherosclerosis. Furthermore, preventive medicine is the most important approach to preventing lifestyle-related diseases, and improving daily nutritional intake is thought to prevent the pathogenesis of such diseases. Therefore, AGEs inhibitors that can be obtained from daily meals are preferred to prescribed drugs. In this article, we describe a strategy for developing new AGEs inhibitors from natural products.

Background: DNA methyltransferase 3A (Dnmt3a) is an enzyme that catalyzes the de novo methylation of DNA, and plays essential roles in a wide range of physiological and pathological processes. However, it remains unclear whether Porphyromonas gingivalis affects cementoblasts, the cells responsible for cementum formation, through Dnmt3a.
Methods: The samples were collected from models of mouse periapical lesions and mice of different ages, and the expression of Dnmt3a was detected through immunofluorescence.
Background: Alzheimer disease (AD) is a heterogeneous multifactorial neurodegenerative disorder pathologically characterized by Aβ plaques, NFT, neuroinflammation, and synaptic and neuronal loss. The nature of most sAD cases strongly argues for an environmental link. The prominent pathological manifestations in AD patients are abnormal levels of Aβ 1-42 (Aβ42), total tau (t-tau) and p-tau in brain and biofluids.

Objective To explore the clinical features and treatments of Chinese patients with bullous pemphigoid (BP) induced by immune checkpoint inhibitors (ICI). Methods A retrospective analysis was conducted on 18 Chinese patients with ICI-induced BP treated in the Peking Union Medical College Hospital and 14 Chinese patients with this disease reported in the literature.Furthermore,the research data of non-Chinese patients were used for comparison to outline the clinical features and treatment responses of the Chinese patients.

Parkinson's disease (PD) is a chronic, progressive neurological disorder affecting approximately 10 million people worldwide, with prevalence expected to rise as the global population ages. It is characterized by the degeneration of dopamine-producing neurons in the substantia nigra pars compacta, leading to motor symptoms such as tremor, rigidity, bradykinesia, postural instability, and gait disturbances, as well as non-motor symptoms including olfactory disturbances, sleep disorders, and depression. Currently, no cure exists for PD, and most available therapies focus on symptom alleviation.

We aim to investigate whether chemical inhibition of NRF2 transcriptional activity (TA) influences distal colon contractions, particularly in an age-dependent manner in females, and whether it impacts oestrogen receptor signalling in female mice. This study was performed on 3 and 6-month-old female mice treated with ML385 (30 mg/kg) or a vehicle for 7 days (i.p.
